Because the FFT is inherently a block-oriented algorithm, the FFT operates most efficiently when quick access to all input and output samples is supported by a freely-addressable RAM. However, this ...

Cooley and Tukey’s Fast Fourier transform (FFT) represented a major breakthrough that paved the way for many of the electronic conveniences we take for granted today. Without the FFT providing an ...

Although examples have been given showing that the spherical average of the Fourier transform cannot decay always too fast, they usually do not exhibit a single measure decaying sufficiently slow on ...

The hardware bit-reverse and linear-address generator in Fig 1a scrambles a time-domain digital N-sample record. The circuit is primarily meant to scramble data before taking a real-time butterfly FFT ...
